T0 aZZ whom it may concern:

Be it known that I, JOSEPH GAYNOR, a citizen of the United States, and a resident of Jersey City, in the'county of Hudson and Stateof New Jersey; have invented a new and Improved M achinefor Shaping and Forming Fabric Cases, of which the following is a full, clear, and exactdescription;

This invention relates to a machine .for shapin and forming fabric cases with direct re erence tocases which contain musical instruments.

The object the provision can be smoothly stretched over die members of the invention resides in in a simple and efficient manner.

provision of means by whichthe manipulation of the machine one operator is rendered exceedingly simple. 1 i

A still further. object resides in the provision of means whereby various adjustments can be made very easily and quickly during the operation of the-,machine so t-hat it is at alltimes entirely under the control of the one operator; a Another object resides in theprovision ofa means whereby the die members can-be from the other I 7 mg or otherwlse 1n]ur1ng the embossing ormade sectional and the inside thereof pro vided with engraved portions which when pressed on to the surface of the article being formed will create impressions of leather grains and other designs on the article and which when the die is opened and the sections are pulled out, can be lifted die member without scratchengraving.

A further object resides in the provision e f-means whereby with the use ofthe sectional die the pressin and drawing of the fabric on the die mem ers ismade considerably easier than withsolid dies, since the complete process of forming a casing takes only about five or six minutes;

A still further object resides in the particular construction and arrangement of dies and in the character of the materials as hereinafter described and claimed and shown in'the accompanying drawings.

In the drawings which vention in its preferred for Figure 1 is a vertical section through the machine Figure 2 is a plan view of the machine 5' i gure 3 is a transverse vertical section a members;

of means whereby the fabric A further object of the invention isthe illustrate the intaken through theymachine' with theldie Figure '6 is a detailed section through the means for operating the die parts simultaneously; I

Figure 7' is a plan view showing the die Figure 8isa detailed View; a

Figure 9 is a horizontal" section througha modified form of the machinejand Figure '10 is l0-10 of Figure 9'.

In the drawings the preferredform of the invention as shown involves a table 11, supported on legs 12; A die memberlg, preferably a male member, ble 11. A sectional female die member is disposed above themale member 13 and is suitably supported'on a framefcapable of movement in a} vertical direction. [This frame is formed, as shown, of a plurality of standards are fastened to the floor t one end and to, preferably. a channelplate 17 in their upper end. This channel plate 17 is provided with a screw feeding device'represented by thenumeral l8,thelower end of which is connected by a universal joint 19, to'apressure plate 20. This pressure plate bears against the upper end 'offcertain of the frame sections, 14 to connect directly to the upper portion or cover 21 of the female" die member which is" formed of a plurality of sections. Thefemale die member further comprises movable end sections 22 and 23 and movable side sections 24 and 25 as noted ahutting' particularly in Figure The edges of adjacent sections of this die memlher, as shown in Figure 7, are provided with inclined edges, represented by the numeral 2e, forming somewhat of a tapered jeina is fastened to the tacastings '15 having "bores i therein a rather close edged connection themale member the This tapered joint, it will be observed,}permits the sections of the die member to be moved inwardly and outwardly with respect to each other and yet to maintain a so that in fitting the fabric over formation of wrinkles or uneven portions is effectively prevented. To the outer faces of these die sections 22, 23, 24v and 25 there are fastened supporting members or castings 27 which in turnare connected to certain sections 14 of the frame. These sections in turn are connected respectively, to castings 28, of which there are a plurality disposed around the die member. These castings are provided with bores through which shafts of these shafts are connected by sets of bevel gears, represented by the numerals 33 and 34, in pairs So that the movement of one shaft is transmitted to the other simultaneously. Ahandle 35 is connected to the end of. one of these shafts and the movement of this handle will cause the movement of each of the other shafts simultaneously with the movement of the one to which this handle is 1 connected, aS shown part cularly in Figure 28 contains a heli.

6. Each of the castings cal gear 86'adapted to mesh with a worm ear 37 on any one of the above-mentioned shafts. The movementofthe worm gear willwcause the helical gear to rotate, this helical gear being disposed ina chamber 38 formed within the casting and mounted on a squared .end39 of a shaft, 40. The shaft 40 is provided with threaded ends41 and 42 extending into bushings 43 and 44, r The bushing 44' is disposed in thecasting and the bushing43 is. disposed in the supporting member'or casting 27. It will be understood thatrbetwcen each casting 28 and its adjacent supporting member or casting 27 this arrangement of parts is disposed so as totransmit pressure to the casting or supporting member 27 and thence to the section of the female die member to which said supporting member is connected. The casting 28, of course, is' supported and connect-.7

ed to the proper sections 14 of the frame. It will be notedthat there are two sets of pressure transmitting mechanisms as above described disposed adjacent each of the end; and side sections of the female die member. Therefore, the movement of the handle in one directlon or the other :will cause the advance or retreat of theabove-mentioned sections of the female die member simultanism is operated the entire frame, formed is moved either upward neously. :The movement of the upper portion 21 of the female die member is effected by the above-mentioned screw feeding mechanism 18. When this screwsfeedingmechaof the sections 14. or downward, and during the operation the incidental movement of the handle 35 ,will

29, 80, 31 and 32 extend. The ends cause the expansion and contraction of the side members of the die member."

The lower edge ofeach of the lateral side members of the female diemember' is pro vided with a recess 45, seen particularly in F i gure t, in which a'plurality of roller bear ings 46 are suitably mounted. There are preferably two sets of these hearings to each of the lateral sections of the .die member. Disposed beneath the sections of the female die member is a plate or frame4'7, preferably forming oneintegral frame, supported on rods 48 throughout its length,these rods having heads 49' thereon and extending. into housings or sleeves 5 0 connected to the table 11. 5O havethreaded adjusting plugs 51 at their bottoms and also contain springs 52 which hear at their lower ends against the plugs 51 and at their upper ends against theheads 49 and are, arranged 1 to constantly tend-to edges of the lateral These housings 7 hold the rods 48 upward and consequently throughout its length at intervals preferably adjacent the points of the die sections containing, the roller bearings above-mentioned, is provided with an opening 58. Adjacent each of these openings 1 is disposed a bracket. to the frame 47 by means offbolts s5 5.having springs 56 resiliently connecting the bolts with the brackets. 7 These brackets support two gears 57 carrying a chain 58. One of these gears is also associated with and mounted on the same shaft with a ratchet gear 59., With this ratchet gear a rack 60 is adapted to direction only. 7 This rack bar 60 islpivotally mounted on the table 11 and a spring 61 bears against it to hold itagainst the ratchet gear 59. It will be understood, therefore, that in association with each set of roller bearings on thedie sections there is disposed an endless chain and a means including the rack bar to operate it. 'VVhenever there is relative movement between the plate or frame 47 and the table 11 especiallywhen:

the rack bar '60,

posed beneath 'the'edge of the lateral sec-- tions-of the female die member and above the plate or frame 47, whichmay also be termed a gripper plate orframe. It will. therefore, be noted that when the lateral sections of the die member are moved down wardly toward the table 11 there is a ,constant travel of the, chains in a directi-on to feed the'fabrictoward the center of the die sections, and this action constantly taking place as the female member is moved downward over the male member of the die will 54 connected co-op'erate to move itin one the gripper frame 47 can this manner the.

overcome the presence of means of a key 68 fully in contact with the fabric,

preventthewrinkling of the fabric'asit is the corners of the male being stretched over member. It will also be observed that this action is entirely automatic. Of course, the resistance of the bars t8 'to the depression of i be adjusted by means of. the plug fabric can be stretched tightly over the male member in a perfectly smooth and even manner, eliminating the necessity for adopting various expedients' to wrinkles.

As shown in Figure 8, I may mount each of the worm gears so that itcan-slide along said shaft although rotating therewithq 1 also may provide collars 64 spaced on'the shaft beyond the end of the worm gear 37 anddispose springs 65 between the ends of the worm gear and said collars so that It will be noticed from a consideration of Figures 1, 2 and'3, that the cover section 21 of the female die member is provided at each end with erossbars 7 8. These bars project'fbeyond theedges of the section 21 and receive rollers 74 mounted in brackets 75. These brackets are connected rigidly to the lateral sections of the female die member and by riding on the ends of the bars 73 provide a firm support to maintain these lateral sections at the proper level with respect to the cover section 21.

In .the modification shown in Figure 9, the female member is one integral section 66, hollow. and the male member is formed of a plurality of sections similar to the 01- mation of the female member previously described in the preferredform of the invention. In this instance I provide a shaft 67 )rovided with a suitable differential gearing arrangement represented by the numeral 68 and connected at theirfouter ends to the inner faces of the lateral sections 70 of the male member. This shaft 67 canbe operated by a handle 71 to effect the simultaneous movement of the sections forward or backward. In other respects the operation of the device and the mechanisms are the same as previonsly described. c

7 In the operation of the deviceI dispose 'a 51 above referred to. Iii

mechanism, which I 37 on its proper shaft by.

arrangement adapted to actuate rods 69 the gripperplate or frame and then the die members toward each other so that one will fit accurately within the other. After they have been moved so that the male member projects fully within the female member and during this fitting I manipulate the handle'35, or the handle 71, as the case may be, to exert the proper pressure of the sections on the fabric and against the other die member; During the time that the'die members are approaching each' other the called the shaping mechanism, including the chain 58 and correlated parts, is operating to :eliminate or prevent the formation of wrinkles at the corners of the case in the fabric. During the time that the fabric is being treated. and stretched over the male die member and the proper pressure is gradually being applied,

heat is being applied to the die members, preferably through the gas pipe 72, to the outer surface of one of the members. During the process, this heat is continually applied, a single process requiring onlyfrom five to six minutes.
